TABLE OF CONTENTS

INDUSTRY AND MARKET DATA

In this prospectus, we rely on and refer to information and statistics regarding the steel processing industry and our market share in the sectors in which we compete. We obtained this information and these statistics from sources other than us, which we have supplemented where necessary with information from publicly available sources, discussions with our customers and our own internal estimates. References in this prospectus to:

We use these sources and estimates and believe them to be reliable, but we cannot give you any assurance that any of the projected results will be achieved.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, together with the other information contained in this prospectus, before making your decision to invest in shares of our common stock. We cannot assure you that any of the events discussed in the risk factors below will not occur. These risks could have a material and adverse impact on our business, results of operations, financial condition and cash flows. If that were to happen, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Relating to Our Business

We service industries that are highly cyclical, and any downturn in our customers’ industries could reduce our sales and profitability. The economic downturn has reduced demand for our products and may continue to reduce demand until an economic recovery.

Many of our products are sold to industries that experience significant fluctuations in demand based on economic conditions, energy prices, seasonality, consumer demand and other factors beyond our control. These industries include manufacturing, electrical products and transportation. We do not expect the cyclical nature of our industry to change.

The U.S. economy entered an economic recession in December 2007, which spread to many global markets in 2008 and 2009 and affected Ryerson and other metals service centers. InBeginning in late 2008 and 2009,continuing through 2010, the metals industry, including Ryerson and other service centers, felt additional effects of the worsening recessionglobal economic crisis and recovery thereto and the impact of the credit market disruption. These events contributed to a rapid decline in both demand for our products and pricing levels for those products. The Company has implemented a number of actions to conserve cash, reduce costs and strengthen its competitiveness, including curtailing non-critical capital expenditures, initiating headcount reductions and reductions of certain employee benefits, among other actions. However, there can be no assurance that these actions, or any others that the Company may take in response to further deterioration in economic and financial conditions, will be sufficient.

The volatility of the market could result in a material impairment of goodwill.

We evaluate goodwill on an annual basis and whenever events or changes in circumstances indicate potential impairment. Events or changes in circumstances that could trigger an impairment review include significant underperformance relative to our historical or projected future operating results, significant changes in the manner or the use of our assets or the strategy for our overall business, and significant negative industry or economic trends. We test for impairment of goodwill by calculating the fair value of a reporting unit using an income approach based on discounted future cash flows. Under this method, the fair value of each reporting unit is estimated based on expected future economic benefits discounted to a present value at a rate of return commensurate with the risk associated with the investment. Projected cash flows are discounted to present value using an estimated weighted average cost of capital, which considers both returns to equity and debt investors. The income approach is subject to a comparison for reasonableness to a market approach at the date of valuation. Significant changes in any one of the assumptions made as part of our analysis, which could occur as a result of actual events, or further declines in the market conditions for our products, could significantly impact our impairment analysis. An impairment charge, if incurred, could be material.

The global financial and banking crises have caused a lack of credit availability that has limited and may continue to limit the ability of our customers to purchase our products or to pay us in a timely manner.

In climates of global financial and banking crises, such as those from which we are currently experiencing,recovering, the ability of our customers to maintain credit availability has become more challenging. In particular, the financial viability of many of our customers is threatened, which may impact their ability to pay us amounts due, further affecting our financial condition and results of operations.

The metals distribution business is very competitive and increased competition could reduce our gross margins and net income.

The principal markets that we serve are highly competitive. The metals distribution industry is fragmented and competitive, consisting of a large number of small companies and a few relatively large companies. Competition is based principally on price, service, quality, production capabilities, inventory availability and timely delivery. Competition in the various markets in which we participate comes from companies of various sizes, some of which have greater financial resources than we have and some of which have more established brand names in the local markets served by us. Increased competition could force us to lower our prices or to offer increased services at a higher cost, which could reduce our profitability.

The economic downturn has reduced metals prices. Though prices have recently started rising,risen since the onset of the economic downturn, we cannot assure you that prices will continue to rise. Changing metals prices may have a significant impact on our liquidity, net sales, gross margins, operating income and net income.

The metals industry as a whole is cyclical and, at times, pricing and availability of metal can be volatile due to numerous factors beyond our control, including general domestic and international economic conditions, labor costs, sales levels, competition, levels of inventory held by other metals service centers, consolidation of metals producers, higher raw material costs for the producers of metals, import duties and tariffs and currency exchange rates. This volatility can significantly affect the availability and cost of materials for us.

We, like many other metals service centers, maintain substantial inventories of metal to accommodate the short lead times and just-in-time delivery requirements of our customers. Accordingly, we purchase metals in an effort to maintain our inventory at levels that we believe to be appropriate to satisfy the anticipated needs of our customers based upon historic buying practices, contracts with customers and market conditions. When metals prices decline, as they did in 2008 and 2009, customer demands for lower prices and our competitors’ responses to those demands could result in lower sale prices and, consequently, lower margins as we use existing metals inventory. Notwithstanding recent price increases, metals prices may decline in 2010,2011, and declines in those prices or further reductions in sales volumes could adversely impact our ability to maintain our liquidity and to remain in compliance with certain financial covenants under the Ryerson Credit Facility, as well as result in us incurring inventory or goodwill impairment charges. Changing metals prices therefore could significantly impact our liquidity, net sales, gross margins, operating income and net income.

We have a substantial amount of indebtedness, which could adversely affect our financial position and prevent us from fulfilling our obligations under our notes.financial obligations.

We currently have a substantial amount of indebtedness.indebtedness and may incur additional indebtedness in the future. As of December 31, 2009,2010, after giving effect to this offering and the application of net proceeds from this offering, our total indebtedness would have been approximately $632$         million and we would have had approximately $390$         million of unused capacity under Ryerson’sthe Ryerson Credit Facility. Our substantial indebtedness may:

We may be able to incur substantial additional indebtedness in the future. The terms of the Ryerson Credit Facility and the indentureindentures governing our outstanding notes restrict but do not prohibit us from doing so. If new indebtedness is added to our current debt levels, the related risks that we now face could intensify.

The covenants in Ryerson’sthe Ryerson Credit Facility and the indentureindentures governing our notes and Ryerson’s notes impose, and covenants contained in agreements governing indebtedness that we incur in the future may impose, restrictions that may limit our operating and financial flexibility.

Ryerson’sThe Ryerson Credit Facility and the indentureindentures governing theour notes contain a number of significant restrictions and covenants that limit our ability and the ability of our restricted subsidiaries, including Ryerson Inc., to:

The terms of the Ryerson Credit Facility require that, in the event availability under the facility declines to a certain level, we maintain a minimum fixed charge coverage ratio at the end of each fiscal quarter. Total credit availability is limited by the amount of eligible accounts receivable and inventory pledged as collateral under the agreement insofar as the Company is subject to a borrowing base comprised of the aggregate of these two amounts, less applicable reserves. As of December 31, 2010, total credit availability was $317.0 million based upon eligible accounts receivable and inventory pledged as collateral.

Additionally, subject to certain exceptions, the indenture governing Ryerson’s notes restrictrestricts Ryerson’s ability to pay us dividends to the extent of 50% of future net income, once prior losses are offset. Future net income is defined in the indenture governing the notes as net income adjusted for, among other things, the inclusion of dividends from joint ventures actually received in cash by Ryerson, and the exclusion of: (i) all extraordinary gains or losses; (ii) a certain portion of net income allocable to minority interest in unconsolidated persons or investments in unrestricted subsidiaries; (iii) gains or losses in respect of any asset sale on an after tax basis; (iv) the net income from any disposed or discontinued operations or any net gains or losses on disposed or discontinued operations, on an after-tax basis; (v) any gain or loss realized as a result of the cumulative effect of a change in accounting principles; (vi) any fees and expenses paid in connection with the issuance of Ryerson’s notes; (vii) non-cash compensation expense incurred with any issuance of equity interest to an employee; and (viii) any net after-tax gains or losses attributable to the early extinguishment of debt. Our future indebtedness may contain covenants more restrictive in certain respects than the restrictions contained in the Ryerson Credit Facility and the indentureindentures governing theour notes. Operating results below current levels or other adverse factors, including a significant increase in interest rates, could result in our being unable to comply with financial covenants that are contained in the Ryerson Credit Facility or that may be contained in any future indebtedness. If our indebtedness is in default for any reason, our business, financial condition and results of operations could be materially and adversely affected. In addition, complying with these covenants may also cause us to take actions that are not favorable to holders of theour notes and may make it more difficult for us to successfully execute our business strategy and compete against companies that are not subject to such restrictions.

We may not be able to generate sufficient cash to service all of our indebtedness.

Our ability to make payments on our indebtedness depends on our ability to generate cash in the future. Our outstanding notes, the Ryerson Credit Facility and our other outstanding indebtedness are expected to account for significant cash interest expenses. Accordingly, we will have to generate significant cash flows from operations to meet our debt service requirements. If we do not generate sufficient cash flow to meet our debt service and working capital requirements, we may be required to sell assets, seek additional capital, reduce capital expenditures, restructure or refinance all or a portion of our existing indebtedness, or seek additional financing. Moreover, insufficient cash flow may make it more difficult for us to obtain financing on terms that are

acceptable to us, or at all. Furthermore, Platinum has no obligation to provide us with debt or equity financing and we therefore may be unable to generate sufficient cash to service all of our indebtedness.

Because a substantial portion of our indebtedness bears interest at rates that fluctuate with changes in certain prevailing short-term interest rates, we are vulnerable to interest rate increases.

A substantial portion of our indebtedness, including the Ryerson Credit Facility and the 2014 Notes, bears interest at rates that fluctuate with changes in certain short-term prevailing interest rates. As of December 31, 2009,2010, Ryerson Holding’s subsidiaries had approximately $102.9 million of floating rate debt under the 2014 Notes and approximately $250.2$457.3 million of outstanding borrowings under the Ryerson Credit Facility, with an additional $268.0$317.0 million available for borrowing under such facility. Assuming a consistent level of debt, a 100

basis point change in the interest rate on our floating rate debt effective from the beginning of the year would increase or decrease our fiscal 20092010 interest expense under the Ryerson Credit Facility and the 2014 Notes by approximately $3.5$4.7 million on an annual basis. We use derivative financial instruments to manage a portion of the potential impact of our interest rate risk. To some extent, derivative financial instruments can protect against increases in interest rates, but they do not provide complete protection over the long term. If interest rates increase dramatically, we could be unable to service our debt which could have a material adverse effect on our business, financial condition, results of operations or cash flows.

We may not be able to sustain the annual cost savings realized as part of our recent cost reduction initiatives.

Since 2007, we have implemented approximately $180 million of what we believe are permanent cost savings on an annualized basis. The cost savings have come primarily as a result of the following initiatives: decentralization of our operations, process improvements in inventory management, closure of under-performing facilities and reduction in our North American headcount. We may not be able to sustain all, or any part, of these cost savings on an annual basis in the future, which could have an adverse effect on our business, financial condition, results of operations and cash flows.debt.

We may not be able to successfully consummate and complete the integration of future acquisitions, and if we are unable to do so, we may be unable to increase our growth rates.

We have grown through a combination of internal expansion, acquisitions and joint ventures. We intend to continue to grow through selective acquisitions, but we may not be able to identify appropriate acquisition candidates, obtain financing on satisfactory terms, consummate acquisitions or integrate acquired businesses effectively and profitably into our existing operations. Restrictions contained in the agreements governing our notes, the Ryerson Credit Facility or our other existing or future debt may also inhibit our ability to make certain investments, including acquisitions and participations in joint ventures.

Our future success will depend on our ability to complete the integration of these future acquisitions successfully into our operations. After any acquisition, customers may choose to diversify their supply chains to reduce reliance on a single supplier for a portion of their metals needs. We may not be able to retain all of our and an acquisition’s customers, which may adversely affect our business and sales. Integrating acquisitions, particularly large acquisitions, requires us to enhance our operational and financial systems and employ additional qualified personnel, management and financial resources, and may adversely affect our business by diverting management away from day-to-day operations. Further, failure to successfully integrate acquisitions may adversely affect our profitability by creating significant operating inefficiencies that could increase our operating expenses as a percentage of sales and reduce our operating income. In addition, we may not realize expected cost savings from acquisitions, which may also adversely affect our profitability.

We may not be able to retain or expand our customer base if the North American manufacturing industry continues to erode through moving offshore or through acquisition and merger or consolidation activity in our customers’ industries.

Our customer base primarily includes manufacturing and industrial firms. Some of our customers operate in industries that are undergoing consolidation through acquisition and merger activity; some are considering or have considered relocating production operations overseas or outsourcing particular functions overseas; and some customers have closed as they were unable to compete successfully with overseas competitors. Our facilities are predominately located in the United States and Canada. To the extent that our customers cease U.S. operations, relocate or move operations overseas to regions in which we do not have a presence, we could lose their business. Acquirers of manufacturing and industrial firms may have suppliers of choice that do not include us, which could impact our customer base and market share.

Certain of our operations are located outside of the United States, which subjects us to risks associated with international activities.

Certain of our operations are located outside of the United States, primarily in Canada, Mexico and China. We are subject to the Foreign Corrupt Practices Act (“FCPA”), which generally prohibits U.S. companies and their intermediaries from making corrupt payments or otherwise corruptly giving any other thing of value to foreign officials for the purpose of obtaining or keeping business or otherwise obtaining favorable treatment, and requires companies to maintain adequate record-keeping and internal accounting practices to accurately reflect the transactions of the company.practices. The FCPA applies to covered companies, individual directors, officers, employees and agents. Under the FCPA, U.S. companies may be held liable for actions taken by strategic or local partners or representatives. If we or our intermediaries fail to comply with the requirements of the FCPA, governmental authorities in the United States could seek to impose civil and/or criminal penalties, which could have a material adverse effect on our business, operations, financial conditions and cash flows.penalties.

Operating results may fluctuate depending on the season.experience seasonal fluctuations.

A portion of our customers experience seasonal slowdowns. Our sales in the months of July, November and December traditionally have been lower than in other months because of a reduced number of shipping days and holiday or vacation closures for some customers. Consequently, our sales in the first two quarters of the year are usually higher than in the third and fourth quarters.

Damage to our information technology infrastructure could harm our business.

The unavailability of any of our computer-based systems for any significant period of time could have a material adverse effect on our operations. In particular, our ability to manage inventory levels successfully largely depends on the efficient operation of our computer hardware and software systems. We use management information systems to track inventory information at individual facilities, communicate customer information and aggregate daily sales, margin and promotional information. Difficulties associated with upgrades, installations of major software or hardware, and integration with new systems could have a material adverse effect on results of operations. We will be required to expend substantial resources to integrate our information systems with the systems of companies we have acquired. The integration of these systems may disrupt our business or lead to operating inefficiencies. In addition, these systems are vulnerable to, among other things, damage or interruption from fire, flood, tornado and other natural disasters, power loss, computer system and network failures, operator negligence, physical and electronic loss of data, or security breaches and computer viruses.

Any significant work stoppages can harm our business.

As of December 31, 2009,2010, we employed approximately 3,5003,600 persons in North America and 450600 persons in China. Our North American workforce was comprised of approximately 1,800 office employees and approximately 1,7001,800 plant employees. Forty-twoForty percent of our plant employees were members of various unions, including the United Steel Workers and the International Brotherhood of Teamsters unions. Our relationship with the various unions has generally has been good. There havehas been twoone work stoppages at Integris Metals’ facilitiesstoppage over the last five years (both prior to Ryerson’s acquisition of Integris Metals): a strike by the members of the International Brotherhood of Teamsters Local #221, a union covering 69 individuals, which occurred at the Minneapolis (Integris) facility in June 2003 and lasted less than one month; and a strike by the members of the International Brotherhood of Teamsters Local #938, a union covering 81 individuals, at the Toronto (Integris) facility, which began on July 6, 2004, and ended when a settlement was reached on October 31, 2004. On January 31, 2006, the agreement with the joint United Steelworkers and the International Brotherhood of Teamsters unions, which represent approximately 540 employees at three Chicago area facilities, expired. The membership of the joint unions representing the Chicago-area employees initiated a week-long strike on March 6, 2006. On July 9, 2006, the joint United Steelworkers and Teamster unions representing the Chicago-area employees ratified a three-year collective bargaining agreement, lasting through March 31, 2009.

In 2007, we reached agreement on the renewal of 10 collective bargaining agreements covering 374 employees. Six collective bargaining agreements expired in 2008, a year in which we reached agreement on the renewal of four contracts covering 53 employees. Two contracts covering 52 employees were extended into 2009. We reached agreement in 2009 on one of the extended contracts covering 45 employees and the single remaining contract from 2008, covering approximately sevenfive persons, remains on an extension. In addition, negotiations over a new collective bargaining agreement at a newly certified location employing four persons began in late 2008 and was concluded in 2009. Nine contracts covering 339 persons were scheduled to expire in 2009. We reached agreement on the renewal of eight contracts covering approximately 258 persons and one contract covering approximately 81 persons has beenwas extended. During 2010, the parties to this extended contract covering two Chicago area facilities agreed to sever the bargaining unit between the two facilities and bargaining was concluded for one facility, which covers approximately 50 employees. This new contract expires on December 31, 2011. The other

facility’s contract, which covers approximately 31 employees, remains on extension. Seven contracts covering approximately 85 persons were scheduled to expire in 2010. We reached agreement on the renewal of all seven contracts. Ten contracts covering approximately 293 persons are scheduled to expire in 2010 covering approximately 85 persons.2011. One of these contracts, which covers 50 employees, will not be renewed due to facility closure. We may not be able to negotiate extensions of these agreements or new agreements prior to their expiration date. As a result, we may experience additional labor disruptions in the future. A widespread work stoppage could have a material adverse effect on our results of operations, financial position and cash flows if it were to last for a significant period of time.

Certain employee retirement benefit plans are underfunded and the actual cost of those benefits could exceed current estimates, which would require us to fund the shortfall.

As of December 31, 2009,2010, our pension plan had an unfunded liability of $323$306 million. Our actual costs for benefits required to be paid may exceed those projected and future actuarial assessments to the extent that those costs exceed the current assessment. Under those circumstances, the adjustments required to be made to our recorded liability for these benefits could have a material adverse effect on our results of operations and financial condition and cash payments to fund these plans could have a material adverse effect on our cash flows. We may be required to make substantial future contributions to improve the plan’s funded status, which may have a material adverse effect on our results of operations, financial condition or cash flows.status.

Future funding for postretirement employee benefits other than pensions also may require substantial payments from current cash flow.

We provide postretirement life insurance and medical benefits to approximately half of oureligible retired employees. Our unfunded postretirement benefit obligation as of December 31, 20092010 was $174$176 million. Our actual costs for benefits required to be paid may exceed those projected and future actuarial assessments to the extent that those costs exceed the current assessment. Under those circumstances, the adjustments will be required to be made to our recorded liability for these benefits could have a material adverse effect on our results of operations and financial condition and cash payments to fund these plans could have a material adverse effect on our cash flows.benefits.

Any prolonged disruption of our processing centers could harm our business.

We have dedicated processing centers that permit us to produce standardized products in large volumes while maintaining low operating costs. AnyWe may suffer prolonged disruption in the operations of any of these facilities, whether due to labor or technical difficulties, destruction or damage to any of the facilities or otherwise, could materially adversely affect our business and results of operations.otherwise.

If we are unable to retain and attract management and key personnel, it may adversely affect our business.

We believe that our success is due, in part, to our experienced management team. Losing the services of one or more members of our management team could adversely affect our business and possibly prevent us from improving our operational, financial and information management systems and controls. In the future, we may need to retain and hire additional qualified sales, marketing, administrative, operating and technical personnel, and to train and manage new personnel. Our ability to implement our business plan is dependent on our ability to retain and hire a large number of qualified employees each year. If we are unable to hire sufficient qualified personnel, it could have a material adverse effect on our business, results of operations and financial condition.

Our existing international operations and potential joint ventures may cause us to incur costs and risks that may distract management from effectively operating our North American business, and such operations or joint ventures may not be profitable.

We maintain foreign operations in China.Canada, China and Mexico. International operations are subject to certain risks inherent in conducting business in, and with, foreign countries, including price controls, exchange controls, export controls, economic sanctions, duties, tariffs, limitations on participation in local enterprises, nationalization, expropriation and other governmental action, and changes in currency exchange rates. While we believe that our current arrangements with local partners provide us with experienced business partners in foreign countries, events or issues, including disagreements with our partners, may occur that require attention of our senior executives and may result in expenses or losses that erode the profitability of our foreign operations or cause our capital investments abroad to be unprofitable.

Lead time and the cost of our products could increase if we were to lose one of our primary suppliers.

If, for any reason, our primary suppliers of aluminum, carbon steel, stainless steel or other metals should curtail or discontinue their delivery of such metals in the quantities needed and at prices that are competitive, our business could suffer. The number of available suppliers could be reduced by factors such as industry consolidation and bankruptcies affecting steel and metal producers. For the year ended December 31, 2009,2010, our top 25 suppliers represented approximately 78%77% of our purchases, and our largest supplier accounted for approximately 15% of our purchases. We could be significantly and adversely affected if delivery were disrupted from a major supplier. If, in the future, we were unable to obtain sufficient amounts of the necessary metals at competitive prices and on a timely basis from our traditional suppliers, we may not be able to obtain such metals from alternative sources at competitive prices to meet our delivery schedules, which could have a material adverse effect on our sales and profitability.

We could incur substantial costs in order to comply with, or to address any violations or liability under, environmental, health and safety laws that could significantly increase our operating expenses and reduce our operating income.

Our operations are subject to various environmental, health and safety statutes and regulations, including laws and regulations governing materials we use. In addition, certain of our operations are subject to foreign, federal, state and local environmental laws and regulations that impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage and disposal of solid and hazardous wastes and remediation of contaminated soil, surface waters and groundwater. Failure to maintain or achieve compliance with these laws and regulations or with the permits required for our operations could result in substantial operating costs and capital expenditures, in addition to fines and civil or criminal sanctions, third party claims for property damage or personal injury, worker’s compensation or personal injury claims, cleanup costs or temporary or permanent discontinuance of operations. Certain of our facilities are located in industrial areas, have a history of heavy industrial use and have been in operation for many years and, over time, we and other predecessor operators of these facilities have generated, used, handled and disposed of hazardous and other regulated wastes. Environmental liabilities could exist, including cleanup obligations at these facilities or at off-site locations where materials from our operations were disposed of, which could result in future expenditures that cannot be currently quantified and which could have a material adverse effect on our financial position, results of operations or cash flows.quantified. Future changes to environmental, health and safety laws or regulations, including those related to climate change, could result in material liabilities and costs, constrain operations or make such operations more costly for us, our suppliers and our customers.

We are subject to litigation that could strain our resources and distract management.

From time to time, we are involved in a variety of claims, lawsuits and other disputes arising in the ordinary course of business. These suits concern issues including product liability, contract disputes, employee-related matters and personal injury matters. It is not feasible to predict the outcome of all pending suits and claims, and the ultimate resolution of these matters as well as future lawsuits could have a material adverse effect on our business, financial condition, results of operations or cash flows or reputation.

We may face product liability claims that are costly and create adverse publicity.

If any of the products that we sell cause harm to any of our customers, we could be exposed to product liability lawsuits. If we were found liable under product liability claims, we could be required to pay substantial monetary damages. Further, even if we successfully defended ourself against this type of claim, we could be forced to spend a substantial amount of money in litigation expenses, our management could be required to spend valuable time in the defense against these claims and our reputation could suffer,suffer.

The volatility of the market could result in a material impairment of goodwill.

We evaluate goodwill on an annual basis and whenever events or changes in circumstances indicate potential impairment. Events or changes in circumstances that could trigger an impairment review include significant underperformance relative to our historical or projected future operating results, significant changes in the manner or the use of our assets or the strategy for our overall business, and significant negative industry or economic trends. We test for impairment of goodwill by calculating the fair value of a reporting unit using an income approach based on discounted future cash flows. Under this method, the fair value of each reporting unit is estimated based on expected future economic benefits discounted to a present value at a rate of return commensurate with the risk associated with the investment. Projected cash flows are discounted to present value using an estimated weighted average cost of capital, which considers both returns to equity and debt investors. The income approach is subject to a comparison for reasonableness to a market approach at the date of valuation. Significant changes in any one of the assumptions made as part of our analysis, which could harmoccur as a result of actual events, or further declines in the market conditions for our business.products, could significantly impact our impairment analysis. An impairment charge, if incurred, could be material.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2010, we had U.S. federal net operating loss carryforwards totaling approximately $110 million, which expire on December 31, 2030. Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and certain other pre-change tax attributes to offset its post-change income may be limited significantly. In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. It is not expected that the offering will result in an “ownership change.” However, because the potential existence and amount of our “5-percent shareholders,” if any, resulting from the offering is not within our control, there is no assurance that the offering will not result in an ownership change. Moreover, even if an ownership change does not result from the offering, subsequent events over which we will have little or no control (including changes in the direct and indirect ownership of our 5- percent shareholders) may cause us to experience an ownership change in the near future. An ownership change could significantly limit the future use of our pre-change tax attributes and thereby significantly increase our future tax liabilities.

Our risk management strategies may result in losses.

From time to time, we may use fixed-price and/or fixed-volume supplier contracts to offset contracts with customers. Additionally, we may use foreign exchange contracts and interest rate swaps to hedge Canadian dollar and floating rate debt exposures. These risk management strategies pose certain risks, including the risk that losses on a hedge position may exceed the amount invested in such instruments. Moreover, a party in a hedging transaction may be unavailable or unwilling to settle our obligations, which could cause us to suffer corresponding losses. A hedging instrument may not be effective in eliminating all of the risks inherent in any particular position. Our profitability may be adversely affected during any period as a result of use of such instruments.

We may be adversely affected by currency fluctuations in the U.S. dollar versus the Canadian dollar and the Chinese renminbi.

We have significant operations in Canada which incur the majority of their metal supply costs in U.S. dollars but earn the majority of their sales in Canadian dollars. Additionally, we have significant assets in China. We may from time to time experience losses when the value of the U.S. dollar strengthens against the Canadian dollar or the Chinese renminbi, which could have a material adverse effect on our results of operations. In addition, we will be subject to translation risk when we consolidate our Canadian and Chinese subsidiaries’ net assets into our balance sheet. Fluctuations in the value of the U.S. dollar versus the Canadian dollar or Chinese renminbi could reduce the value of these assets as reported in our financial statements, which could, as a result, reduce our stockholders’ equity.

Risks Relating to Our Common Stock and this Offering

There is no existing market for our common stock, and we do not know if one will develop to provide you with adequate liquidity.

Prior to this offering, there has not been a public market for our common stock. We cannot predict the extent to which investor interest in our company will lead to the development of an active trading market on the New York Stock Exchange (“NYSE”), or otherwise, or how liquid that market might become. If an active trading market does not develop, you may have difficulty selling any of our common stock that you buy in this offering. Consequently, you may not be able to sell our common stock at prices equal to or greater than the price you paid in this offering. In addition, an inactive trading market may impair our ability to raise additional capital by selling shares and may impair our ability to acquire other companies by using our shares as consideration.

The initial public offering price of the shares has been determined by negotiations between the Company and representativesthe representative of the underwriters. Among the factors considered in determining the initial public offering price were our record of operations, our current financial condition, our future prospects, our markets, the economic conditions in and future prospects for the industry in which we compete, our management, and currently prevailing general conditions in the equity securities markets, including current market valuations of publicly traded companies considered comparable to our company. We cannot assure you, however, that the prices at which the shares will sell in the public market after this offering will not be lower than the initial public offering price or that an active trading market in our common stock will develop and continue after this offering.

Our stock price may be volatile, and your investment in our common stock could suffer a decline in value.

The stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock. The initial public offering price for our common stock was determined by negotiations between the Company and representativesthe representative of the underwriters and may not be indicative of prices that will prevail in the open market following this offering. You may not be able to resell your shares at or above the initial public offering price due to fluctuations in the market price of our common stock caused by changes in our operating performance or prospects, including possible changes due to the cyclical nature of the metals distribution industry and other factors such as fluctuations in metals prices, which could cause short-term swings in profit margins. If the market price of our ordinary shares after this offering does not exceed the initial public offering price, you may not realize any return on your investment in us and may lose some or all of your investment. In addition, companies that have historically experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.concerns.

Future sales of our common stock in the public market could lower our share price.

We may sell additional shares of common stock into the public markets after this offering. The market price of our common stock could decline as a result of sales of a large number of shares of our common stock in the public markets after this offering or the perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities at a time and at a price that we deem appropriate.

After the consummation of this offering, we will have         71,029,412 shares of common stock outstanding. Of the remaining         71,029,412 outstanding shares, 47,500,000,5,000,000, or     67%,%, of our total outstanding shares will be restricted from immediate resale under the “lock-up” agreements between us and all of our directors, officers and stockholders

and the underwriters described in the section entitled “Underwriting” below, but may be sold into the market after those “lock-up” restrictions expire, in certain limited circumstances as set forth in the “lock-up” agreements, or if they are waived by both Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC as the representativesrepresentative of the underwriters, in theirits discretion. The outstanding shares subject to the “lock-up” restrictions will generally become available for sale following the expiration of the lock-up agreements, which is 180 days after the date of this prospectus, subject to the volume limitations and manner-of-sale requirements under Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”).

This offering will cause immediate and substantial dilution in net tangible book value.

The initial public offering price of a share of our common stock is substantially higher than the net tangible book value (deficit) per share of our outstanding common stock immediately after this offering. Net tangible book value (deficit) per share represents the amount of total tangible assets less total liabilities, divided by the number of shares of common stock outstanding. If you purchase our common stock in this offering, you will incur an immediate dilution of approximately $11.18$             in the net tangible book value per share of common stock based on our net tangible book value as of December 31, 2009.2010. You may experience additional dilution if we issue common stock in the future. As a result of this dilution, you may receive significantly less than the full purchase price you paid for the shares in the event of a liquidation. See “Dilution.”

Our controlling stockholder and its affiliates will be able to influence matters requiring stockholder approval and could discourage the purchase of our outstanding shares at a premium.

Prior to this offering, Platinum owned 99% of our outstanding common stock. Upon completion of this offering, Platinum will continue to control all matters submitted for approval by our stockholders through its

ownership of approximately     66%% of our outstanding common stock. These matters could include the election of all of the members of our Board of Directors, amendments to our organizational documents, or the approval of any proxy contests, mergers, tender offers, sales of assets or other major corporate transactions.

The interests of Platinum may not in all cases be aligned with your interests as a holder of common stock. For example, a sale of a substantial number of shares of stock in the future by Platinum could cause our stock price to decline. Further, Platinum could cause us to make acquisitions that increase the amount of the indebtedness that is secured or senior to the Company’s existing debt or sell revenue-generating assets, impairing our ability to make payments under such debt. Additionally, Platinum is in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with us. Accordingly, Platinum may also pursue acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us. In addition, Platinum may have an interest in pursuing acquisitions, divestitures and other transactions that, in their judgment, could enhance their equity investment, even though such transactions might involve risks to you as a holder of our common stock. For example on January 29, 2010, we closed an offering (the “Ryerson Holding Offering”) pursuant to which we issued the Ryerson Holding Offering,Notes, 96% of the gross proceeds of which were paid to Platinum as a cash dividend. Moreover, weWe intend to use a portion of the net proceeds from this offering to redeem in full the Ryerson Holding Notes. See “Use of Proceeds.”

We are exempt from certain corporate governance requirements since we are a “controlled company” within the meaning of the NYSE rules and, as a result, you will not have the protections afforded by these corporate governance requirements.

Because Platinum will control more than 50% of the voting power of our common stock after this offering, we are considered to be a “controlled company” for purposes of the NYSE listing requirements. Under the NYSE rules, a “controlled company” may elect not to comply with certain NYSE corporate governance requirements, including (1) the requirement that a majority of our Board of Directors consist of independent directors, (2) the requirement that the nominating and corporate governance committee of our Board of Directors be composed entirely of independent directors, (3) the requirement that the compensation committee of our Board of Directors

be composed entirely of independent directors and (4) the requirement for an annual performance evaluation of the nomination/corporate governance and compensation committees. Given that Platinum will control a majority of the voting power of our common stock after this offering, we are permitted, and have elected, to opt out of compliance with certain NYSE corporate governance requirements. Accordingly, you will not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance requirements.

If we fail to maintain effective internal control over financial reporting, our business, operating results and stock price could be adversely affected.

Beginning with our annual report for our fiscal year ending December 31, 2011, Section 404 of the Sarbanes-Oxley Act of 2002 (“Section 404”), will require us to include a report by our management on our internal control over financial reporting. This report must contain an assessment by management of the effectiveness of our internal control over financial reporting as of the end of our fiscal year and a statement as to whether or not our internal controls are effective. OurTo the extent we become an accelerated or large accelerated filer, our annual reports, beginning with our annual report for the fiscal year ending December 31, 2011, must also contain a statement that our independent registered public accounting firm has issued an attestation report on the effectiveness of our internal control over financial reporting.

In order to achieve timely compliance with Section 404, we have begun a process to document and evaluate our internal control over financial reporting. Our efforts to comply with Section 404 have resulted in, and are likely to continue to result in, significant costs, the commitment of time and operational resources and the diversion of management’s attention. If our management identifies one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. If we are unable to assert that our internal control over financial reporting is effective, or if

our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal control over financial reporting, market perception of our financial condition and the trading price of our stock may be adversely affected and customer perception of our business may suffer.

Our corporate documents and Delaware law will contain provisions that could discourage, delay or prevent a change in control of the Company.

Our amended and restated certificate of incorporation and amended and restated bylaws will contain provisions that may make the acquisition of our company more difficult without the approval of our Board of Directors. These provisions:

These anti-takeover provisions and other provisions under Delaware law could discourage, delay or prevent a transaction involving a change in control of our company, even if doing so would benefit our stockholders.

These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause us to take other corporate actions you desire.

Any issuance of preferred stock could make it difficult for another company to acquire us or could otherwise adversely affect holders of our common stock, which could depress the price of our common stock.

Upon completion of this offering, our Board of Directors will have the authority to issue preferred stock and to determine the preferences, limitations and relative rights of shares of preferred stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our stockholders. Our preferred stock could be issued with voting, liquidation, dividend and other rights superior to the rights of our common stock. The potential issuance of preferred stock may delay or prevent a change in control of us, discouraging bids for our common stock at a premium over the market price, and adversely affect the market price and the voting and other rights of the holders of our common stock.

We do not intend to pay regular cash dividends on our stock after this offering.

We do not anticipate declaring or paying regular cash dividends on our common stock or any other equity security in the foreseeable future. The amounts that may be available to us to pay cash dividends are restricted under our debt agreements. Any payment of cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions and other factors deemed relevant by our Board of Directors. Therefore, you should not rely on dividend income from shares of our common stock. For more information, see “Dividend Policy.” Your only opportunity to achieve a return on your investment in us may be if the market price of our common stock appreciates and you sell your shares at a profit but there is no guarantee that the market price for our common stock after this offering will ever exceed the price that you pay for our common stock in this offering.

FORWARD-LOOKING STATEMENTS

This prospectus contains “forward-looking statements.” Such statements can be identified by the use of forward-looking terminology such as “believes,” “expects,” “may,” “estimates,” “will,” “should,” “plans” or “anticipates” or the negative thereof or other variations thereon or comparable terminology, or by discussions of strategy. Readers are cautioned that any such forward-looking statements are not guarantees of future performance and may involve significant risks and uncertainties, and that actual results may vary materially from those in the forward-looking statements as a result of various factors. Among the factors that significantly impact the metals distribution industry and our business are:

These forward-looking statements involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Forward-looking statements should, therefore, be considered in light of various factors, including those set forth in this prospectus under “Risk Factors” and the caption “Industry and Operating Trends” included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this prospectus. Moreover, we caution you not to place undue reliance on these forward-looking statements, which speak only as of the date they were made. We do not undertake any obligation to publicly release any revisions to these forward-looking statements to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the         23,529,412 shares of common stock that we are offering will be approximately $372$         million after deducting the underwriting discount and estimated offering expenses of $28.0$         million and assuming an initial public offering price of $17.00$         per share, the mid-point of the estimated initial public offering price range. A $1.00 increase (decrease) in the assumed initial public offering price of $17.00$         per share would increase (decrease) the net proceeds from the sales of shares of common stock that we are offering by $22.1$         million after deducting the underwriting discount and estimated offering expenses of $1.4$         million.

We intend to use our net proceeds from the sale of shares of our common stock offered pursuant to this prospectus and the net proceeds from the exercise, if any, of the underwriters’ over-allotment option (i) to redeem in full the Ryerson Holding Notes, plus pay accrued and unpaid interest and additional interest, if any, up to, but not including, the redemption date, (ii) with respect to 50% of any remaining net proceeds following the redemption described in clause (i), subject to certain exceptions, to make an offer to repurchase Ryerson Inc.’s 12% Senior Securedthe 2015 Notes due 2015 at par and (iii) with respect to the remaining 50%, to repay outstanding indebtedness under the Ryerson Credit Facility and (iv) to pay related fees and expenses. ThoughTo the extent that there can be no assurance that holders of Ryerson Inc.’s 12% Senior Notes due 2015, which are currently trading above par, will accept ouradditional remaining proceeds after the offer to repurchase such notes at par, if a sufficient number of holders accept our offer such that the full 50% of remaining net proceeds referred to in clause (ii) of the proceeding sentence are used to repurchase such notes, thenabove, we expect towill repay outstanding indebtedness under the Ryerson Credit Facility.Facility and pay related fees and expenses as provided in clause (iii) above. See “Underwriting.” The Ryerson Credit Facility matures on the earliest of (i) March 2016, (ii) 90 days prior to the scheduled maturity date of the 2014 Notes, if any 2014 Notes are then outstanding and (iii) 90 days prior to the scheduled maturity date of the 2015 Notes, if any 2015 Notes are then outstanding. The weighted average interest rate on the borrowings under the Ryerson Credit Facility was 2.1% at December 31, 2010. For additional information about the terms of the Ryerson Credit Facility, see “Description of Certain Indebtedness.” We used the proceeds from the issuance of the Ryerson Holding Notes in January 2010 to: (i) pay a cash dividend to our stockholders and (ii) pay fees in connection with the Ryerson Holding Offering and related expenses. This prospectus is not an offer to purchase, a solicitation of an offer to purchase or a solicitation of a consent with respect to the Ryerson Holding Notes or the 2015 Notes.

We will not receive any proceeds resulting from any exercise by the underwriters of the over-allotment option to purchase additional shares from the selling stockholders identified in this prospectus. In the aggregate, if the over-allotment is exercised, the selling stockholders will receive approximately $56.4$         million after deducting the underwriting discount and estimated offering expenses of $3.6$         million and assuming an initial public offering price of $17.00$         per share, the mid-point of the estimated initial public offering price range.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and our total capitalization as of December 31, 20092010 (1) on a historical basis and (2) on an as adjusted basis assuming the closing of the Ryerson Holding Offering and giving effect to the use of proceeds therefrom and (3) on an as further adjusted basis to give effect to the Services Agreement Termination, the sale of shares of our common stock offered hereby assuming an initial public offering price of $17.00$         per share, the mid-point of the estimated initial public offering price range, and the application of the net proceeds as described in “Use of Proceeds.Proceeds,” and the Services Agreement Termination.

You should read this table together with the information contained in “Use of Proceeds,” “Selected Consolidated Financial Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related financial information contained elsewhere in this prospectus.

The number of shares of our common stock shown as issued and outstanding in the table above excludes (i)         3,529,412 shares of our common stock that may be purchased by the underwriters to cover over-allotments and (ii) 3,800,000          shares of common stock reserved for future grants under our stock incentive plan (assuming our stock incentive plan, which is described in “Executive Compensation—Stock Incentive Plan,” is adopted in connection with this offering).

DILUTION

Dilution is the amount by which the offering price paid by the purchasers of our common stock to be sold in this offering will exceed the net tangible book value per share of our common stock immediately after this offering. The net tangible book value per share presented below is equal to the amount of our total tangible assets (total assets less intangible assets) less total liabilities as of December 31, 2009,2010, divided by the number of shares of our common stock that would have been held by our common stockholders of record immediately prior to this offering after giving effect to the         9.50 for 1.00 stock split. Our net tangible book value as of December 31, 2009,2010, was approximately $70.5$         million, or $1.48$         per share. After giving effect to the sale of the shares of common stock we propose to offer pursuant to this prospectus at an assumed public offering price of $17.00$         per share, the mid-point of the range of estimated initial public offering prices set forth on the cover page of this prospectus and the application of the net proceeds therefrom, and after deducting the underwriting discount and estimated offering expenses, our net tangible book value as of December 31, 20092010 would have been $413.1$         million, or $5.82$         per share. This represents an immediate dilution in net tangible book value of $        11.18 per share.

The following tables illustrate this dilution:

A $1.00 increase (decrease) in the assumed initial public offering price of $17.00$         per share (the mid-point of the range on the cover page of this prospectus) would (decrease) increase our net tangible book value (deficit) by $22.1$         million, the net tangible book value (deficit) per share after this offering by $0.31$         per share and the decrease in net tangible book value (deficit) to new investors in this offering by $0.69$         per share, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses.

The following table summarizes the number of shares purchased from us and the total consideration and average price per share paid to us, by existing holders of common stock, and the total number of shares purchased from the Company, the total consideration paid to the Company and the price per share paid by new investors purchasing shares in this offering:

If the underwriters’ over-allotment option is exercised in full:

DIVIDEND POLICY

We have in the past paid cash dividends to our stockholders. See “Certain Relationships and Related Party Transactions—Dividend Payments.” We do not currently anticipate declaring or paying regular cash dividends on our common stock in the foreseeable future. Any payment of cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions, including restrictions contained in our existing debt documents or the terms of any of our future debt or other agreements that we may enter into from time to time, and other factors deemed relevant by our Board of Directors. See “Description of Certain Indebtedness,” and “Description of Capital Stock—Common Stock.”
